Just my 2-cents as a pax who loves to eat.
Happy flying.
Your FRA crew simply didn't follow proper procedure for the meals. They preferred to be lazy. Typical FRA attitude. Of course, I'd never have accepted a cold chocolate fondue. That's like serving a frozen steak.
Don't forget to write some feedback to LH, comparing the national disgrace of your FRA experience with your much better MUC experience.
